The present invention relates to a novel catalyst having a stable catalytic activity for catalyzing the reaction of an alcohol with carbon monoxide and oxygen to produce carbonic acid esters (i.e., carbonate), and also the present invention relates to a method of producing carbonic acid esters using this catalyst. The catalyst of the present invention comprises a copper halide and at least one hydroxide compound selected from a group consisting of alkali metal hydroxides and alkali earth metal hydroxides carried on a porous carrier, and also provide a process of regenerating a catalytic activity of the catalyst.
a présente invention porte sur un nouveau catalyseur qui catalyse de façon stable la réaction d'un alcool et de l'oxyde de carbone et de l'oxygène produisant des esters d'acide carbonique (c.-à-d. des carbonates); elle porte aussi sur une méthode de production d'esters d'acide carbonique employant ce catalyseur. Ce catalyseur comprend un halogénure de cuivre et au moins un composé du type hydroxyde choisi parmi des hydroxydes de métaux alcalins et des hydroxydes de métaux alcalino-terreux portés sur un support poreux; un procédé de régénération du catalyseur est fourni.
